Ah that's a good idea. Though - in my mind - there is little opportunity that a command that an immortal has access too will have a help file too high for them to read. If that's the case, it's probably a mistake.

I've seen it happen and yes, it's usually just a case of whoever wrote the help file not making sure to set the level properly to reflect that of the command it's meant to reference. Could also have been a case of a holder file where the coder made a help file with every intention of actually writing it up and forgetting about it. *shrug*

Either way it lets people know that there's a help file issue one way or another, even if it's just a case of needing to play with the level a little, which can be handy.

Plus you can also do it with the list of commands using that, well, command.
